Firstly, don't BBQ on a wild camp. Remember in the UK and Wales, you are trespassing, unless you have the land owners permission. Nothing winds a land owner up more than flames.
There's a guy on You Tube, with a Jimney (new style) who camps in his vehicle - actually looks very comfortable
Wild camping on lanes is difficult. There's rarely any room. Ideally you want to camp in the vehicles footprint, so inside or underneath; or very close to, but out of the ruts/mud. Have you looked at Hammocks?
I have an awning. Just a cheap unbranded version of the generic chinese one that ARB use. It's 3m long by 2.5m pull out. I mount it to Roof bars. Works fine. Easy to remove. I use it for static wild camping - useually for long periods of foot travel. Awnings are never as easy to set up as they look, added to which they don't like bad weather. And , again, as mentioned before, there needs to be room for them at the side of a lane.
When I lane camp, I use a basha, or two, a bouncing bomb in a bivvy bag, with additional face net and a folding camp bed. I've done that in the snow, torrential rain and fine days. It's a fifteen minute set up and very comfy. I do have an air pocket matress for the bed, as my back is shot. Everything is done for the fast get away, as it's a criminal offence to obstruct the highway. Food is cooked, in a slow cooker, during the day (actually two slow cookers. both drawing 200w). No alchohol is consumed... Far better to find a site like Nash Oaklands, Cocco's or Gaerwen, then just use a tent
